2016-12-12Fix edge cases in orphan section placement.Cary Coutant1-3/+32
There were still some cases I found where orphan section placement was screwy -- where the script has no output section description for either .data or .bss, a .bss orphan section ends up getting placed before the .data section. In addition, if there is an output section description for a data section not named .data (e.g., .rela.dyn), the orphan .bss gets placed before it. This patch cleans that up, by tracking the last allocated section even as we're adding orphans. I've also improved segment layout in the absence of a PHDRS clause. A zero-length NOBITS section will no longer force a new segment when followed by a PROGBITS section. 2016-12-12 Cary Coutant <ccoutant@gmail.com> gold/ * script-sections.cc (Orphan_section_placement::update_last_alloc): New method.

2016-12-11Fix problems with bss handling in linker scripts.Cary Coutant1-20/+45
PR 16711 noted that gold allocates file space for BSS sections when using a linker script. I've fixed that by rewriting set_section_addresses and set_section_list_addresses to track the file offset separate from the current virtual address, so that BSS sections do not move the file offset. Now, if a series of BSS sections come at the end of a segment, we do not allocate file space; but if a script forces them into the middle of a segment, we will still allocate file space (matching Gnu ld behavior). I've also added a warning when that happens. That exposed another problem where orphan .bss sections were sometimes placed in the middle of a segment. For example, if the script mentions the .got section, but both .data and .bss are orphans, gold would put both .data and .bss in front of .got. I've fixed that by ensuring that orphan BSS sections are always placed after all other allocated sections. It also exposed a problem where the SUBALIGN property is not handled properly. The ld manual clearly states that it should override input section alignment, whether greater or less than the given alignment, but gold would only increase an input section's alignment. Gold would also place the output section based on its original alignment before the SUBALIGN property took effect, leading to a misaligned output section (where the input section was properly aligned in memory, but was not aligned relative to the start of the section), in violation of the ELF/gABI spec. I've fixed that by making sure that the SUBALIGN property overrides the internal alignment of the input sections as well as the external alignment of the output section. This affected the behavior of script_test_2, which was written to expect a misaligned section. The net effect is, I think, improved compatibility with the BFD linker. There are still cases where orphan placement differs, but the differences should be rarer and less important. ALIGN and SUBALIGN behavior is closer, but still not an exact match -- I still found cases where ld would create a misaligned output section, and where gold will properly align it. gold/ PR gold/16711 * output.cc (Output_section::set_final_data_size): Calculate data size based on relative offset rather than file offset.

2015-08-26Fix problem where script specified both address and region for a section.Cary Coutant1-18/+43
If a script specifies both address and region for an output section declaration, gold ignores the region specification. This can lead to bogus "moves backward" errors. This patch fixes gold so that if a section specifies both address and region, it will place the section at the specified address in the region, and update the location counter within the region. gold/ PR gold/18847 * script-sections.cc (Memory_region::set_address): New method.

2015-06-03Fix SIZEOF_HEADERS in gold.Cary Coutant1-3/+21
Gold undercounts the number of program headers it's going to add when initially evaluating the SIZEOF_HEADERS expression. As a result, scripts that use it end up skipping a page unnecessarily when the starting address is too low. The undercounting is because it doesn't count the PT_INTERP segment. Then, when finalizing symbols, gold overcounts the program headers: all segments have already been created, but we still count the headers we expected to add from the script. This patch fixes both problems. gold/ * script-sections.cc (Script_sections::Script_sections): Initialize segments_created_.

2015-06-03Fix gold to group sections correctly via linker script.Cary Coutant1-1/+27
In PR 15370, it is noted that gold does not distinguish between "*(.foo .bar)" and "*(.foo) *(.bar)" in linker scripts. In both cases, gold groups all .foo sections together, followed by all .bar sections, whereas in the first case, it should collect all .foo and .bar sections in the order seen. If you add sort specs, the Gnu linker has some bizarre corner cases that I do not try to replicate. In particular, "*(SORT_BY_NAME(.foo) SORT_BY_NAME(.bar))" does the same thing as "*(.foo) *(.bar)". But if you apply a sort spec to just one of several patterns, say, "*(SORT_BY_NAME(.foo) .bar)", the Gnu linker will collect any .bar section it sees before the first .foo, then all .foo sections, then all remaining .bar sections. With this patch, if any of the input patterns have a sort spec, gold will group them all as it did before; e.g., all .foo sections followed by all .bar sections. 2015-06-03 Cary Coutant <ccoutant@gmail.com> gold/ PR gold/15370 * script-sections.cc (Output_section_element_input::set_section_addresses): When there are several patterns with no sort spec, put all sections in the same bin. * testsuite/Makefile.am (script_test_12): New testcase.
